Application led April 29, 1826. Serial No. 105,350.

This invention relates in general to snow plows for removing snow from streets, roads, or highways, the apparatus embodylng an impeller or rotor for receiving and delivering the snow from the machlne, and a scoop like device for gathering and directing the -snow to the impeller.

In machines of this character it has been found that the snow will pack within the scoop and will pile 11p-at times to such an extent that it will fall out of the frontof the scoop. in advance of the machine, with the result that the operation of the machine will be impaired.

It isv one of the objects of the present invention to provide improved means in con' nection with the scoop for assisting in conveying the snowv to .the impeller, and for breaklng up and disintegrating the snow as Vit ifs delivered tol the impeller or rotor.

A further object is to provide improved means for use in connection with the. scoop for breaking up the snow which has accumulated and become packed- -with'in the scoop, andfor feeding and transferring the snow from the top of the pack or pile to the rotor orimpeller to be delivered thereby from the machine.

' To the attainment of these ends and the accomplishment of otherl new and useful objects as will appear, the invent-ion consists in the features of novelty in substantially the construction, combination, and arrangement of the several parts, hereinaftery more fully described and claimed and shown inthe acvention; and in which,

able manner upon the structure and is v shaped to contain a rotor of any suitable construction. The rotor is operated from a' power shaft 16 through the medium of inl termeshing gears 17, 18, 19 the gears being so arranged with respect to each other that the casing 12 may be swung about its pivot without interfering with the operation of the rotor.

Associated with vthe casing12- is a scoop.-

like device 20 having its forward end open and arranged to direct the snow into the casing 12 through the opening 13 and to the rotor 12. 1

Arranged at the bottom of the scoop are a plurality of shafts 21 extending le hwise thereof, and these shafts are preferab y provided with blades 22 for propellinilthe snow,

land additional blades 23'for brea disintegrating'the snow.

Any number of these shafts 2l and blades may be provided. The forward ends of lthe shafts are preferably mounted in .suitable bearings 24 and the rear ends in suitable bearings 25, the latter being preferably located in the rear of the 'scoop and theshafts pass through suitable openings in a cover portion 26.

The bearings 25 are preferably formed in the wall of a casing 27, and within the casing is arranged a shaft 28 having gears 29 thereon which mesh with the gears 30 on the ends of the shafts 21 for rotating them.

. Motion is imparted to the shaft 28 through the mediuml of a gear 31 connected thereto outside of the casing 27, and this gear 4meshes with a gear 32 on a shaft 33 mounted in suitable bearings 34. Connected with the shaft 33 isl another gear 35 which meshes with `a gear 36 on a shaft 37 to which the gear 18 is connected...

Thus it will be seen that when the shaft 37 is rotated through lthe drive shaft. 16, the rotor 1 5 will be rotated, and motion will be impartedto the shafts 21 for rotating the Iblades, 22 to assist in feeding the snow through the yscoop and into the opening .13 toA the impeller 15..

Journaled in suitable bearings in the sides ofthe scoop is a casing 38 within which is a shaft 39 that has bearings ,in the end of the casing. One end `of the shaft 39 projects through the lend of the caslng 38 and also one of the side walls of the scoop, and

has connected therewith a gear 40 which meshes with a gear 41 on a shaft 42.

A gear 43 is also connected with the shaft 42 and meshes with a gear 44 on the 's ha bearin na ed at one end in bearin V47 for assisting in feeding the snow tothe im ller. i f

onnected with each of the shafts 47 and witlinathe casing 38 are gears 49, whichV mesh with the gears 50 on the shaft 3,9 for part-ing rotation to the shaft '47 and theL blades 48. l

` The casing 38 is adapted to be rotated 1n its bearings so as toraise and lower the shaft 47 and the blades 48 connected there. to, -tocause them to bodily move in directions toward and. away from the bottom ,of the scoop. These shafts 47 and blades 48 are so arranged that they will operate upon Athe vtopv of the ile of. the accumulated or packed snow vwithin the scoop toassist in, feeding it to the rotor.

Any suitable means may be provided for moving the casing 38 aboutits ivot to raiser and lowerthe shafts 47 and b ades 48 and v to maintain them in their adjusted position.

-the groun To that end there may beaprovided a' worm gear 51 whichI is connected with .the casing 38 preferably on the utside of the scoop, Meshin with this wo m gear is a worm `52 provi ed with a handle 53 for rotating it; lBy rotating the worm 52 a rotary movement will be impartedv to the casing 38, so4 that the shafts 47w1th the blades 48 thereon 'ma be moved in directions toward and awa rom the bottom ofthe scoop, as indicate Ain Figure l andwithout interfering with the rotation ofthe shafts '47.
